OGRAX-VENT air duct fire protection system (OGRAX-BM + OGRAX-K adhesive)
Fire protection of air ducts with OGRAX-BM foil-faced basalt material on OGRAX-K adhesive; EI 60 and EI 90 ratings.

OGRAX-M has the widest temperature range among the OGRAX cable compounds: from −60 to +250 °C. The coating, made of a polymer with mineral fillers in an organic solvent, is weather-resistant, works at humidity up to 100% and is suitable for flood-prone cables. It can be applied from −25 °C; work is carried out with the voltage switched off and in compliance with the rules for handling flammable liquids. Compliance with GOST R 53311-2009 is confirmed by a TR EAEU 043/2017 certificate; the service life is at least 30 years.
